Having spent some years patrolling A roads and Motorways I have lost count of how many vehicles got punctures at speed 70ish and by the time they could pull over the tyre was shredded, all the gunk in the world won't help that. First thing I did with my Ford ST was buy a space saver from flea bay. Sadly with my wife's Audi they have put the battery in the wheel well so I can't do the same.
Absolutely. spot on, the wife's Merc has no spare tyre as its been taken up by the Ad blue tank, so if a tyre shreds then you are stuck. She had Smarts for years with no spare and we put a glup inside the tyre that's supposed to seal the puncture almost instantaneously, which did work with the exception of one blowout caused by hitting a plank of wood (which fell off the lorry in front of us) and completely deflated the tyre and partially off the rim..
